Specification of Letters Patent.

Patented June 12, 1906.

Application filed September 14,1905. Serial No. 278,408.

To all whom it may concern:

Be it known that I, GEORGE HOLDEN, of Merchantville, county of Camden, and State of New Jersey, have invented an Improvement in Window-Screens, of which the following is a specification.

My invention has reference to windowscreens; and it consists of certain im rovements which are fully set forth in the ollowing specification and shownin the accompanying drawings, which form a part thereof.

Heretofore window screens .have been made with a spring-roller attached to the lower bar of the lower sash-frame and from which the screen'of cloth has depended and attached at its lower edge to the window-sill, so that as the window-sash .is raised the screen is unwound from the roller, 'ust filling the space exposed by the raising of the sash, and, conversely, when the window-sash is lowered the screen automatically winds up upon the roller. This construction, while having general utility, had several defective and unsatisfactory features, among which may be mentioned that the attachment of the screen directly to the window-sill was objectionable, in that it was necessary to remove the screws to permit the screen to be detached when it was not desired to have the screen in the window, and aside from the inconvenience of such attachment the screwholes in the window-sill were a t to permit rotting thereof by penetration of water when the screen was not in place. Furthermore, where the window-sill was not level or where the roller was not attached to the windowsash absolutely accurately at right'an les to the travel of the sash the screen wou d not adjust itself so as to be taut at each side or selva e and would thereby vibrate and allow t e insects to pass into the room. Further, the edges of the screen were not held against the action of drafts when the window-sash was fully raised, and consequently the desired security against the passage of insects was ve ineflectual.

' The object df my invention is to provide a constructlonof window-screen of the general nature of that above referred to, but which shall obviate the defects mentioned .and

which shall, furthermore, embod in its construction many details adapted or the more practical and convenient use of a screen of this nature.

My invention consists of a spring-roller attachment adapted, to be secured to the Window-sash and from which a suitable screen depends, the lower edge of which is combined with an end bar pivotedto a base-ba'radapted to be held in position adjacent to the Window-sill, whereby the screen may adjust itself automatically with respect to its attachment to the window-sill.

My invention further consists in combining the above features with socket portions secured to the side of the window-frame and with which the base-bar detachably interlocks and by which it is held in position close to the window-sill without any direct con' nection with said window-sill.

My invention further embodies in 'a Win dow-screen of the general character described a construction in which there are vertical side bars a ainst which the lateral or selvage ed es of t e screen rest and to which they are c amped at suitable places to hold them in place when the window-sash is raised to a considerable extent.

My invention also embodies in the construction last mentioned suitable cam devices on the Window-sash or the frame carrying the spring-roller for operatingthe clamps on the side bars, so that when the window-- sash is raised or lowered the clamps will be automatically opened at the proper time to release the window-screen or closed to permit it to be clamped, as will be more fully understood from the description to follow.

My invention also embodies details of construction which, together with the features above mentioned, will be better understood by Freference to the drawings, in which 1 dow ame andsash with my improvements applied thereto, and taken on line a; a: of Fi Fig. 2 is an elevation of the same wit the Window-sash slightly raisedj Fig. 3 is. a vertical section of the same on line y' y of Fig. 2. Fig. 4 is a vertical spring-roller and its su porting-frame, taken on line if t of Fig. 6. Fig. '5 is a perspective view of one end of the spring-roller-supporting frame.

end of the screen and the lower partof one of the side bars. Fig. 8 is a perspective view of a portion of the side bars, showing the clamp.

Fig. 7 is a per- 'spective view showing the bars for the lower ure 1 is a cross-section through a Winsection through the Fig. 9 is a vertical section through the screen and its attachments when removed from the spring-roller; and Fig. 10 is an enlarged sectional view of the spring-roller, showing the sash B by screws passing through the lug C These lugs have elongated holes 0, so as to permit a slight adjustment of the frame C, whereby buckling or uneven tension on the screen may be obviated, as aforesaid. The

case C comprises two parts 0 and C, telescoping into each other and leaving an open throat C through which the screen may pass. The parts C and C are closed at their outer ends by end plates C, which are rovided with cams H and also the aforesaid ugs C as clearly shown in Fig. 5. The spring-roller is clearly shown in Figs. 4, 6, and 10. It consists of a wooden part D, to one endof which is secured a metallic sleeve D having a pivot d, journaled in one of the end frames D. The other end of the wooden part D is fitted with a second metallic sleeve D inclosing the spring G and the spindle G,

which is provided with the usual rectangular end fitting a corresponding hole in the other end plate C of the frame C. One end of the spring G is secured to the spindle G and the other end is secured to the wooden part D.

By this construction it is evident that the j length of the roller may be increased or decreased to suit the length of the frame C, which is made to correspond to the particular width of the window-sash. This adj'ustability of the parts D and C is a great convenience in the manufacture, as it permits these parts to be adapted to any particular width of window without material expense and without having to keep an unreasonable stock of the goods of various lengths on the hands of the manufacturer. The sleeves D and D are formed with longitudinal ooves D which have an over han ing shou der D The sleeves are formed, pre erably, by bending a sheet of metal into a cylinder with the particular method of joining the ends shown in Fig. 10, which forms the groove and overhanging shoulder.

The-wooden part D of the roller is simply formed with a groove D", into which the grooved portions of the sleeves extend, as will be clearly understood from the drawings. The screen E may be made of any suitable material, but preferably of suitably-sized mesh mosquito-netting. The upper end is secured to a transverse flat rod L, which is inserted in the groove D of the roller, the edgesunder the overhanging shoulder, as indicated in Fig. 10, so that any pull upon the screen cannot pull the rod out of the groove. This is a simple and inexpensive method of securing the screen to the roller and, moreover, does not interfere with the rod being removed when necessary.

The lower end of the screen E is clamped to a transverse frame F, which comprises an end bar F and a bottom bar F secured together by a single pivot f. The bottom bar is preferably U-shaped, and between the upwardly-extending parts thereof the lower edge of the end bar F extends, as clearly shown in Figs. 7 and 9. In this manner the bar F may be oscillated on the bar F, so as to automatically adjust itself.

The bottom bar F is provided at each end with laterally extending lugs F These lugs are inserted in sockets I on the lower ends of the side bars I, which side bars are secured to the parting-beads immediately outside of the window-sash, as is clearly shown in Figs. 1 and 2. In this manner the bottom bar is readily secured in place and close to the window-sill without any direct attachment to the Window-sash itself. Moreover, the connection between the flanges F and the sockets I is such that the said bottom bar may be coupled and uncoupled with said sockets readily, so that when the screen is not desired to be used the bottom bar may be uncoupled and permitted to rise and fall with the window-sash and remain close up to the frame C containing the spring-roller, it being held in that positlon by the winding action of the roller exerted through the screen.

The side bars I are L-shaped and are screwed to the parting-beads through suitable parts of the window-frame and the lateral edges or selvages of the screen rest against the outer surfaces thereof and hold the said screen from blowing inward. At a distance from the bottom of the bars I suitable clamps J are provided, which are hinged to the bars I and made to close under the action of the coil-springs K. The upper and lower parts of these clamps J are flanged outwardly, as at J, and these parts are in alinement with the travel of the cams H on the frame C. It will now be understood that as the sash is raised the upper cams H in ascent pass under the clamps J and lift them and hold them open until the screen is placed under them. Then as the sash continues to rise the lower cams H allow the clamps J to gradually close and grip the lateral edges of the screen, so as to clamp it firmly against used, and especially in those cases where the Window-sash was raised to a very great distance. In ordinary windowsthe wlndowsash is not raised a distance which would require more than one such clamp on each side; but I do not restrict myself to the particular I number of clamps that might be used.

i is t e frame attached so that it may be an end frame for the lower end dow-sill, and side sockets adjusted vertically at each end or either end to secure roper horizontality, but I have provided t e holding or clamping bar at the bottom of the screen with similar adjustability and of an automatic nature, so that the lateral edges of the screen are induced to remain taut under equal tensions. This is a very important feature in thecommercial application of my invention. a

.While I have shown the construction of my invention in the formin which I have found it mostpraotical for commercial purposes, I do not restrict myself to the minor details, as it is evidenttoone skilled inthe art that these may be materially modified in combining and assembl' g the various parts making up the complete structure.
